摘要：探寻python多线程ctrl+c退出问题解决方案
场景：
经常会遇到下述问题：很多io busy的应用采取多线程的方式来解决，但这时候会发现python命令行不响应ctrl-c 了，而对应的java代码则没有问题：

I have only tested this on Linux. I would expect it to
work on the Macintosh and not work on Windows.
"""
def __init__(self):
""" Creates a child thread, which returns. The parent
thread waits for a KeyboardInterrupt and then kills
the child thread.
"""
self.child = os.fork()
if self.child == 0:
return
else:
self.watch()
def watch(self):
try:
os.wait()
except KeyboardInterrupt:
# I put the capital B in KeyBoardInterrupt so I can
# tell when the Watcher gets the SIGINT
print 'KeyBoardInterrupt'
self.kill()
sys.exit()
def kill(self):
try:
os.kill(self.child, signal.SIGKILL)
except OSError: pass
Watcher()
thread_=threading.Thread(target=foreverLoop)
thread_.start()
注意 watch()一定要放在线程创建前，原因未知。。。。，否则立刻就结束
